First, parking and start
Try to avoid parking the vehicle at the tuyere when parking at night. Try not to drive or hit the throttle immediately after starting the vehicle. Because the vehicles are made of metal, especially inside the engine cylinders, after a night of wind blowing and temperature reduction, the endothermic properties and conductivity of the metal will cause frost inside the engine, and the internal temperature will drop very low, not only It will bring great difficulty to the start of the engine, and the damage to the engine itself is also great. Therefore, try not to drive or bomb the throttle immediately after starting in winter, because the oil should be transported to various parts through the oil pump. If there is no good lubrication, driving and accelerating will definitely cause serious damage to the various parts of the vehicle.
Second, the wiper
If you go out early in the morning and find that the wiper is stuck on the windshield by snow water, do not rinse it directly with hot water. This will easily cause the window to burst due to temperature changes and the wiper deformed. The correct method should be to open the air conditioner to the hot air, the blowing mode is the front windshield, and the wiper is naturally opened.
Third, the cooling system
In the winter, it is necessary to regularly check whether the water tank, water pump and belt, water pipe, water supply tank and other components are working properly. If there is damage or malfunction, it is best to repair or replace it in time. Otherwise, a barrel of antifreeze may be wasted for a small water pipe. In particular, some vehicles have high water temperatures in the summer, and the repairman removes the thermostat. Although it can solve the summer problem, it will be reversed in the winter.
Fourth, warm air
After placing a warm summer wind, there will often be failures. It is best to try whether there is hot air, whether the fan is running or not, and whether the air duct is unobstructed. Sometimes the problem is that the antifreeze in the heater pipe does not flow for a long time, and the condensation blocks the circulation line. Although it does not affect the driving, it is very troublesome to repair.
Five, antifreeze
Check for lack of liquid, deterioration, and if necessary, replenish or replace. Antifreeze seems to be a trivial matter, but it has a great influence on the car. If it is light, it will block the pipeline, and if it is heavy, it will damage the cylinder. Therefore, carefully choose anti-freezing liquid with caution. First, do not mix it. Second, do not use fake and shoddy products. In addition, in general, the antifreeze should be changed once every two years. If the antifreeze of the vehicle has not been replaced for two years or if it has been added by itself, then the owner will go to the store for the freezing point test. If it fails to meet the standard, it should be immediately replace. It is best to rinse the cooling system with clean water before replacing.
Six, motor oil
After the heavy snowfall, the temperature drops suddenly, and you must pay attention to whether the viscosity of the car's oil meets the standard. Because the viscosity of the oil will increase after the temperature drops sharply, it may be greatly affected during cold start. It is difficult to start and the engine is difficult to turn. Therefore, it is recommended that the owner replace the oil with lower viscosity. Generally, the oil in the four seasons can reach zero. It is about Celsius, so replace the higher oil when the temperature continues to decrease.
Seven, windshield
Keeping the windshield clear is the basic condition for safe driving. Wipe the wiper regularly during the winter, and ensure that the windshield can be wiped off in the snow. If necessary, you can change the anti-freeze type windshield to avoid freezing in winter. In addition, some windshield deicer can be added to the glass water. When the windshield is frozen, spray the glass water, and the ice will melt. Unlike the ordinary glass water, the more it is sprayed, the more trouble it will be. Glass water should be of high quality. Because the amount of glass water used after snow will be relatively large, it is recommended that the owner add some higher quality glass water to prevent freezing, because the nozzle has a small aperture and may form a blockage. Once the glass water spout is blocked, the owner should not be nervous. You can go to the store to check the freezing point or place the vehicle in a warm garage.
Eight, the body
After the snow, the road is sprinkled with salt water, and the salt water splashed on the body is very harmful to the paint. Before entering the winter, it is best to add a protective film to the body. Car paint coating or mirror glaze containing Teflon polymer can resist the erosion of acid rain, snow and salt water. Be prepared in advance, and you will not be afraid of ruining the paint when you are traveling in the snow.
Nine, chassis
In winter, the car chassis always deals directly with rain and snow, and it is easy to rust. The speeding tires will smash the snow with high salinity onto the chassis of the car. After the snow cleared, the chassis of the car began to rust. Therefore, it is best to spend some time before entering the winter to make a chassis armor.
Ten, battery
The battery is most afraid of low temperature, and the battery capacity in a low temperature environment is much lower than that at normal temperature. Therefore, before the cold season comes, the electrolyte of the battery should be replenished to adjust the specific gravity of the electrolyte. At the same time, clean the battery terminals and apply special grease to protect them, ensure reliable start-up and extend battery life. If the vehicle is not used for a few weeks in the open air or cold storage, the battery should be removed and stored in a warmer room to prevent the battery from freezing.
Eleven, tires
Tire rubber will harden and be relatively brittle in winter, and the friction coefficient will decrease, so the tire pressure should not be too high, but it should not be too low. The outside temperature is low, the tire pressure is too low, and the soft tire can accelerate the aging. In winter, the inclusions in the tread should be cleaned frequently. Try to avoid using tires that have been replenished more than once, and replace tires with large wear and different brands. The wear inside and outside the tire is very different. To ensure safe and reduce wear, the tire should be replaced regularly.
Twelve, car wash
After the heavy snowfall, the body will definitely be very dirty. It is recommended that the owner go to the professional car wash for cleaning. Especially in the winter in the north, the snow melting agent will be used to clear the snow. If the vehicle is not cleaned in time after snowing, the chemical substances in the snow melting agent will corrode the body. In addition, if you feel that the vehicle has irregular shaking when driving in the snow, you should immediately go to the store to check whether the vehicle has damage to the suspension or the gap is too large.
